Pakistan, May 15 -- A new scientific breakthrough from NASA has shed light on one of the Moon's long-standing mysteries: why its Earth-facing side looks so distinct from the far side we never see. Using data gathered from NASA's twin Gravity Recovery and Interior Laboratory (GRAIL) spacecraft, scientists have discovered fundamental differences in the Moon's internal structure that date back billions of years.

The research, recently published in Nature, reveals that the Moon's nearside is warmer and geologically more active than the farside, largely due to intense volcanic activity in the distant past. This activity led to the accumulation of heat-producing elements like thorium and titanium on the nearside, heating its interior and shapi...
